Machu Picchu
Built for Pachacuti around 1450 and abandoned within a century, the citadel kept its terraces, water channels and doorways because no conqueror is recorded as having reached it. Arrive from Aguas Calientes on the first bus or the last stretch of the Inca Trail, before the cloud lifts, when the ridge appears and disappears as the valley breathes.
Why go
An Inca royal estate, complete — terraces, water channels, temples and housing in their original relationship. Engineering above all — the buildings are famous; the drainage and foundations are the achievement. The setting — a saddle between two peaks with the Urubamba river six hundred metres below on three sides. The approach — the Inca Trail, or the train through the gorge; arrival is half the experience.
The character
Machu Picchu was built for Pachacuti around 1450 as a royal estate — a country residence with farms, staff and religious buildings, occupied seasonally by the Inca court, and home to perhaps seven hundred people. It was abandoned within a century, around the time of the Spanish conquest, though no conqueror is recorded as having reached it. That absence is the whole reason it survives: nothing was demolished, no church was built over the temple, and the stonework stayed as its masons left it.
What makes it extraordinary is not the view but the invisible engineering. Sixty per cent of the construction is underground: crushed rock drainage layers under every terrace, channels that move water from a spring through sixteen fountains, and foundations built for a site with two fault lines and two thousand millimetres of rain a year. The buildings are dry-stone, cut to fit without mortar, and they are still standing on a slope that should have slid centuries ago. Hiram Bingham publicised the place in 1911, but local farmers were cultivating those terraces when he arrived — it was never as lost as the story requires.
Places of character
The Guardhouse terrace — the classic view, and the right place to understand the plan before walking into it. Temple of the Sun — the curved wall over the natural rock, with a window aligned to the June solstice. Intihuatana — the carved stone, one of the few ritual stones the Spanish never destroyed elsewhere. The Sacred Rock and the northern sector — quieter, where the estate becomes a working settlement. Inca Bridge — a cliff path with a removable log section; a five-minute walk most visitors skip. Huayna Picchu or Montaña — the two climbable peaks, both requiring a permit booked months ahead.
The way to do it
Book everything early — entry is timed, circuits are fixed and daily numbers are capped. Sleep in Aguas Calientes and take the first bus at 5.30, or arrive on the Inca Trail through the Sun Gate at dawn, which is the best arrival in South America. Acclimatise in Cusco for two days first; the site is lower than the city, but the trail is not. Hire a guide at the gate and follow the circuit rather than fighting it.
One perfect day
First bus in the dark, through the switchbacks, and up to the Guardhouse as the cloud is still moving through the saddle. Watch the ridge appear and vanish for half an hour before walking anything. Then the circuit slowly with a guide — the Sun Temple, the fountains, the Intihuatana — with attention on the water system over the postcard angles. Climb the Inca Bridge path when the main terraces fill. Down to Aguas Calientes for a late lunch, then the afternoon train through the Urubamba gorge to Ollantaytambo, which has the second-best Inca stonework in Peru and one tenth of the visitors, arriving in time for dinner in the Sacred Valley.
Grand hotels
Belmond Sanctuary Lodge — the only hotel at the gate, plain rooms at an extraordinary price, justified entirely by being inside the fence at dawn. Inkaterra Machu Picchu Pueblo — twelve acres of cloud forest in Aguas Calientes, with orchids and a bird list that make the town bearable.
When to go
Best expression: May and September, dry, clear and outside the July–August peak. Consider: the shoulder weeks of April and October, green from the rains with the crowds thinner. Avoid if possible: February, when the Inca Trail closes for maintenance and rain is constant.
